copper refining process steps


Posted on September 15, 2019



Copper extraction - WikipediaCopper extraction refers to the methods used to obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining.copper refining process steps,Transforming Copper Ore step by stepThe final smelting stage occurs in a refining furnace, where the blister copper is melted with carbon in the presence of oxygen to produce fire-refined copper (99% copper), which is cast into anodes that are shipped to a copper refinery. During the electrolytic refining process the copper anodes are placed in large acid-filled.
